I ordered this product to reduce screen glare caused by the lighting in my room and the window behind my desk. Overall, the product does its job of reducing glare while providing protection from side glances. Adhesive strips are very simple and easy to apply. Both of my monitors are 21.5 inches. I compared the screen on the left with a protective screen and the screen on the right without. As you can see, it reduces brightness and glare and protects your screen's privacy from side glances.
